Technical Product Overview
3DM-GX2™
Gyro Enhanced
Orientation Sensor
Introduction
Features & Benets
3DM-GX2™ is a high-performance gyro enhanced orientation
sensor which utilizes miniature MEMS sensor technology. It
combines a triaxial accelerometer, triaxial gyro, triaxial
magnetometer, temperature sensors, and an on-board processor
running a sophisticated sensor fusion algorithm.
• small, light-weight, low-power design ideal for size-sensitive
applications including wearable devices
3DM-GX2™ oers a range of output data quantities from fully
calibrated inertial measurements (acceleration, angular rate
and magnetic eld or deltaAngle & deltaVelocity vectors) to
computed orientation estimates (pitch & roll or rotation matrix).
All quantities are fully temperature compensated and corrected
for sensor misalignment. The angular rate quantities are further
corrected for G-sensitivity and scale factor non-linearity to third
order.
• simultaneous sampling for improved time integration
performance
3DM-GX2’s communications interface hardware is contained
in a separable module, and can therefore be easily customized.
Currently available interface modules include a wireless
transceiver, USB 2.0, RS232 and RS422. An OEM version is
available without the communications interface enabling the
sensor to be integrated directly into a host system’s circuitboard,
providing a very compact sensing solution.
Applications
• fully temperature compensated over entire operational range
• calibrated for sensor misalignment, gyro G-sensitivity, and gyro
scale factor non-linearity
• available with wireless and USB communication interfaces
• user adjustable data rate (1 to 250Hz) and sensor bandwith
(1 to 100Hz)
• outputs include Euler angles, rotation matrix, deltaAngle &
deltaVelocity, acceleration and angular rate vectors
• inertial aiding INS and GPS, location tracking
• unmanned vehicles, robotics – navigation, articial horizon
• computer science, biomedical – animation, linkage free
tracking/control
• platform stabilization
• antenna and camera pointing
